The effect of light intensity on the growth and yield of E. cardamomum was studied on 5-year-old plants of the cultivar PVI Malabar, grown in Tamil Nadu, India. The light regimes were full, medium and low light (1600, 720-980 and 320-480 micro E m-2 s-1, respectively). The number of suckers/plant, length of suckers, number of leaves/sucker, number and length of panicles/clump, number of capsules and FW and DW of capsules showed maximum values under medium light. There was about a 40% reduction in growth parameters and a 60% reduction in yield characters in plants exposed to full light compared to those exposed to medium light. Plants under low light had growth and yield values intermediate between those in medium and full light.
